Gpu: GTX 1060 6gbs
CPU: I5-9600k
Mobo: Asus Strix z370-E Gaming
Ram: 8gbs DDR4
PSU: Corsair TX 750w
Started a few days ago but whenever I try to play a game I can either play for a bit or it crashes instantly. The monitor will go black and I can here my gpu's fans going full speed as if its over heating. I can still hear game sound and my friends talking in voice chat. I checked drivers and they are all up to date. I recently replaced everything but the PSU as an upgrade from an older system so I think it might be that. Any ideas on what could be wrong would be really appreciated.
